A 16 year old is in custody following a robbery that prompted a lunch-hour lockdown at an Esquimalt High School Monday.

A teen was arrested in connection with the incident Thursday morning and charged with one count of robbery, according to Victoria police.

Police said the suspect isn't a student at Esquimalt High, but stopped short of identifying the person's gender in a news release issued Thurday.

On Monday, police said a man stole a girl's backpack at knifepoint on Colville Road, just down the street from the school. She was not injured in the incident.

She reported the theft to school officials and the facility went into lockdown as police searched for the suspect.

Some students locked themselves in classrooms while other hid underneath tables in the school's library.

After securing the premises, police determined the suspect wasn't on school grounds and continued their search throughout the week.
